VEHICLE TRE.

Application led October 16J 1922. Serial No. 594,830.

enact description.

My invention relates to improvements in vehicle tires, and more particularly to that Vtype of tire which may not be punctured by the introduction of nails r other destructive devices through the tread or casing, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a vehicle tire of the character described in which a pneumatic tube for attaining resiliency is employed, but in which the tube is not disposed adjacent the tread.

A further object of my invention is t0 provide a vehicle tire of the character described in which the pneumatic tube is encased in a rigid casing and therefore effectively shielded from mutilation as in the case of the ordinary7 inner tube which is disposed within the tire casing.

A further object of my invention is to provide a vehicle tire of the character described which possesses a high degree of resiliency that is practically7 iiidestructive except for the natural wear upon the tread.

A further object of my invention is to provide a vehicle tire of the character described in which the casing of which the tread is a. part, may be removed and replaced without deflating or in any way adjusting the pneumatic tube, although it greatly assists the mechanic t0 partially deflate the tube as the casing is adjusted.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1. is a side elevation of an embodiment of my invention, j

Figure 2 is an enlarged fragmentary view of a portion of the mechanism illustrated in Figure 1, and

Figure 3v is a sectional view along the line 3-3 of Figure 2.

In carrying out my invention, I make use of a vehicle wheel 1 having a supporting rim 2. This supporting rim 2 is closer to the hub 3 of the wheel than in the case of the ordinary vehicle Wheel, since the tire I employ is relatively deeper than the ordinary type of vehicle tire.

A wooden'casing 4 comprising two parts 5 and 6 which are bolted together by means of a plurality of bolts 7 and 8, is securely fixed to the rim 2. ln this case, I fix the portion of the casing to the rim 2 and the portion (3 of the casing may be removed to introduce a pneumatic tube for a purpose hereinafter described. The interior of the casing 4 which l choose to call a rigid casing, is provided with arcuate top and bottom Walls and substantially side walls 9. A pneumatic tube 10 0f ordinary size and structure is introduced in the casing 4 and its valve stem 11 is projected through the lower wall of the casing and the rim 2 in precisely the same manner as the valve stem in the ordinary vehicle tire.

A vehicle tire casing 12, substantially the same size and structure as the ordinary type of tire casing, is secured upon the periphery of the rigid casing 4 by means of removable rims 13. The rims 13 are held in place by the bolts 8, which bolts take the place of the lug in the ordinary type of removable rim. The upper wall 14 of the casing 4 is provided with a plurality of openings therethrough equal distances apart on the entire periphery of the casing 4. Each of these openings is provided with a metal bearing member 15. A plunger 16, having a stem 17, is slidably mounted by means of its stem in each of the bearings 15. The plunger 16 is provided with an arcuate supporting surface 18 at its upper end having a curvature substantially parallel ata predetermined distance from the curvature of the inner wall of the casing 12. rIhe plunger 16 is further provided with an arcuate shoe 19 at its lower end. The shoe 19 is fashioned t0 conform with the curvature of the pneumatic tube and is of such width that the shoe may move within the interior of the casing 4 as the plunger 16 is reciprocated.

rlhe stem 17 of the plunger 16 is provided with a longitudinal slot 2O therethrough (see Figure 2). Convoluted resilient rings 21 are disposed in the casing 12, one for each of the plungers 16, and the lower porv 23 are longitudinally disposed Within the easing 12 transverse to the convoluted rings 21. The rings 23 are spaced apartirom one another by their'introduction to the alternate folds soif the ring `21.v The ring' 21l therefore v serves as a spacing member for the rings 23. lt should be understood ol` course that the rings '23 vary Uin diameter, that is, the rings adjacent the lower end of the plunger are ot' course of a smaller diameter than the rings adjacent the top of the plunger. the rings 21 coact to form a flexible supporting and reeniorcing member -for theV otherwise hollow casing 12;

`From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The

`undamentijl principlesof my vehicle tiie are very much similar tothe ordinary vehicle tire in which the tube is disposed immediately adjacent the casing, yet Yin my liinpi'oved tire, the tube isremote from the eX'- terior ot the casing and therefore is not subjected to possible mutilation or puncture due tothe projection of spikes, glass, and the like, through the casing. As the Wheel 1 moves upon the road, only a portion of the Wheel of course is in actualcontact With the road, and the entire Weight supported by the Wheel is supported at that one particular-spot. It would seem therefore after having aV knowledge of the construction of my device, that but one or two of the plungers 16 may -be immediately over the road at one time and therefore what-yielding resistance is precisely theV saine as oltered inthe ordinary type of vehicle `tire and possesses all of the iin- -portant good features., ofthe pneumatic The rings 23 and tire. The rings 23, aswell Aas the rings 21, i

since they are flexible, will tollow'the contour o' theY casing 12 as itiscompressed immediately over theroad, but Willimmediately return to their normal positions, Y

precisely the same effect Vas'that produced in the ordinary type or' pneumatic tire and casing, but Without the disadvantages always present in that type of tire'.

l claim:

1. A device of the characterVV described comprising a resilient tire casing, a reen- `forcing frameconsisting o-a -plurality of resilient metal rings.- Vdisposed within said casing and extendingk longitudinally thereofYV at spaced intervals onthe inner Walls, means for retaining said rings in theirv adjusted spaced relation Withone another relative to the `casing Wall, a rigid casing for supporting said tire casing, plungers radially and slidably disposed in said rigid casing.

and arranged tov extend and contact said reenlorcing frame in said tire casing, and

a pneumatic tube supported in said rigid casing, the inner ends of said plunger being Varranged to rest on said tube.V

2. device of the character describedV comprising a resilient tire casing, a reentorcing trame consisting of a plurality otl resilient rings 'disposed Within the'casing at spaced intervals on the inner Wallthereoif, and undulated ringsV4 disposed transversely to said resilient rings for holding` said rings in their adjusted spaced relation relative to one another, a rigid tire casing for supporting said resilient tire casing, plungei's radially and slidably disposed iiisaid rigid casing and varranged to ,extendV into said resilient casing and contact the inner walls of said reen'torcing vframe,`and a pneumatic tubepdisposed in said rigid casing, theinner ends of said plungerbeing arranged to rest upon said pneumatic tube. i I
